The Roland KC-550 is a keyboard amplifier with a 4-Channel Stereo mixer and 180 Watts of power, built into a 2-way, full-range speaker cabinet with a 15" Woofer and a 1" Horn Tweeter. A 3-Band Master EQ section and a global output Shape switch are included, and each mixer channel has a dedicated volume knob. A Stereo Auxiliary input has also been built into the mixer section.
The KC-550 also features a Stereo Link I/O section for dual unit connection, and XLR lines out for balanced mixer connection; the KC-550 is capable of serving as both a stage monitoring solution and a submixer.
